April 09, 2009

It's time for the latest issue of the Developer Shed newsletter. And it's ABOUT time for mobile platform development to get the respect it so richly deserves. The article we're highlighting for you this week from eWeek shows that it's finally happening. When an institution as respectable as Stanford University offers a course on the subject of applications for the smart phone, you can bet that field has finally arrived. Granted, it's a free, online, 10-week course, but that makes it all the more desirable. Think of learning the skill set as acquiring another tool to put in your developer's toolbox.

This is what we at the Shed do best, after all: give you the tools to help you get your job done. So what's in the toolbox this week? Well, Dev Shed readers enjoyed our continuing series on the Ext JS library, the active record pattern, and challenging users for security purposes with AJAX. If you're planning a migration to Windows Server 2008, you won't want to miss reading ASP Free this week; we ran back-to-back articles on the process. They start you off with the planning stages, which should help keep you from running into problems down the line.

Website designers and developers can always pick up new tips and techniques from Dev Articles, and this week is no exception. We wrapped up two series: one on HTML magic edges and another on building a web page calculator. They're great read together; imagine building a calculator that slides smoothly out of the edges of your web site when your visitors want to use it, and disappears when they're ready to move on to something else. We also continued our comprehensive look at streams in C++. Don't forget that both Dev Articles and Dev Hardware publish five times a week now! Speaking of Dev Hardware, this week's reviews included a power supply unit and two digital cameras...just the thing if you're thinking about a summer vacation.

The SEO professionals reading SEO Chat may have noticed a distinct focus on jobs this week. In addition to the next part of our series on ranking factors, we discussed making money with Internet-based jobs and ways to boost the popularity of your job board. With the current economy, a focus on jobs shouldn't surprise anyone. Those of you who blog might want to check out Dev Mechanic this week; we ran the second part of our two-part series on configuring a WordPress-based web site, discussed the pros and cons of allowing comments on your site, and Friday's article...well, I shouldn't tell you, but it's also devoted to helping bloggers.

We know that's never enough for you, so of course we have more. Web Hosters ran an item on whether you should buy domains solely for their page rank. Codewalkers continued our series on UNIX by taking a close look at the shell. And Tutorialized and Scripts still offer plenty of useful content for your perusal.

As always, thanks for reading. Until next week,
Developer Shed Staff

Using Division Equations to Make Web Forms Safer with Ajax
by Alejandro Gervasio, 2009-04-08

From a web developer's point of view, building a mechanism that permits you to protect online forms against attacks by spam bots, malicious automated submissions, and so forth, can be challenging. Developing such an application often requires using a server-side graphic library to generate the so-called noisy images. However, it is possible to quickly create a similar mechanism with Ajax, without having to work directly with images generated in the web server. This is the fourth part of a four-part series that explains how to do just that.

Adding Scientific Functions to a Web Page Calculator
by Chrysanthus Forcha, 2009-04-08

In this last part of our six-part series, we shall talk about adding scientific functions to our web page calculator, and then conclude. Scientific functions refer to functions like sin(?), cos(?), tan(?), and log(x). The process is not as difficult as you think. The JavaScript interpreter incorporated into many browsers has some built-in scientific functions. It has most of the functions we shall use. However, it does not have some of the functions we shall use. We shall have to code the pair of functions that JavaScript does not have.

The Sony Cybershot DSC-W150 is a mid-range point-and-shoot digital camera that embodies the spirit of middle range point-and-shoot cameras. While the camera technically falls under the category of "ultra compact," the DSC-W150 is a little bulkier than most at 3.7 inches wide, 2.3 inches high, and 0.9 inches deep. Despite that, the camera is as small as you can expect most point-and-shoot digital cameras to be: small enough to stick in a big pocket or a bag. Read on for the details.

The Shell and UNIX
by Gabor Bernat, 2009-04-08

It is dangerous to expose our most important possessions directly to every little effect coming from the world. Somebody may take advantage and just do damage to them. It is wise to put something in front of them. In the case of an operating system, the most important part is the kernel. Furthermore, we can take advantage of putting something in front of it, simplify working with the kernel, and make a couple of checks to ensure that nothing abusive happens. What we add before the kernel is the Shell.

The trick is to give each person just as many rights as he absolutely needs, in such a fashion that he does not get the sense of being restricted.

Future TV May Obey Your Every Move

Those gestures you make at the TV may take on an actual meaning if Hitachi and GestureTek have their way. The two companies are working together to bring a version of remote control to the TV without using a handheld device. Instead, a camera positioned below the set will pick up your hand movements, and allow you to change channels, navigate menus, raise and lower the volume, simply by waving your hands.

Before you get all excited about acting like Tom Cruise in your own version of Minority Report, however, keep in mind that this is still at the prototype stage. Hitachi did demonstrate it at Ceatec last year and at CES in January, but there's no guarantee that it will actually make it to market. That said, GestureTek has been making motion-control software for nearly 20 years, and it has been used in a variety of devices, including cell phones and game consoles.

The hardware presents a challenge. The remoteless remote uses a depth camera to spot predetermined gestures (meaning that you can gesture in three dimensions and the camera will understand it). As you would expect, such cameras are expensive; they cost 10 to 20 times what you would expect to pay for a web cam. William Leckonby, CEO of GestureTek, thinks the price will come down in the next year and a half, to $50 per camera. That's low enough for TV manufacturers to consider including them in their premium models. It may be worth paying a little extra to never lose the remote again...though fighting over control of it could take on a whole new meaning.

Car Need Batteries? Grow Your Own

Normally, the process of producing lithium ion batteries is hard on the environment: it involves highly reactive components, high temperatures, and very nasty solvents, to say nothing of the hazards of handling lithium. Anything that can make it cleaner and safer to manufacture these batteries, which power everything from electronic gadgets to hybrid cars, is welcome. Now, scientists have successfully turned to genetically engineered viruses for a solution.

Angela Belcher and her team at the Massachusetts Institute of Technology took a harmless virus dubbed M13 and inserted two genes into it: one that makes the virus produce proteins that bond with iron and phosphate ions, and another that creates a protein at the tip of the virus that bonds to a carbon nanotube. When you combine these two processes, you end up with tubular virus particles sheathed in iron phosphate, becoming nanowires, with a tip that conducts electricity. They had, in short, a cathode, and since they'd previously used a virus to make an anode, creating the full battery was relatively simple.

This is a battery, but is it any good? According to the team's tests, it's as good as the best commercially available lithium ion batteries. They now have a fully virus-based, 3-volt lithium ion battery that can easily power an LED. The creation process does not involve high temperatures, harsh chemicals or fancy equipment. Best of all, the battery is as efficient as the best of what we have today, and it's effectively a first draft. Belcher thinks they can boost their battery's performance using the same basic production system.

Library of Congress Launches YouTube Channel

You've seen some amazing things on YouTube, but nothing quite like this. The Library of Congress made its way onto the wildly popular video website with its own channel this week. The move follows hot on the heels of the organization's collaboration with Flickr to bring thousands of non-copyrighted images to the photo sharing web site.

So what has the LOC chosen to share? The channel currently offers 70 historical videos, including the first moving image ever (of a man sneezing), century-old films from the studio of Thomas Edison, and industrial films featuring Rosie the Riveter. This is the tiniest fraction of the Library's six million video collection, and more are coming. LOC Director of Communications Matt Raymond insisted on the organization's public blog that they're not going to just upload a bunch of videos and walk away.

This probably won't be the last time you see the Library of Congress collaborating with a new media web site, either. Plans are in the works to distribute some of the library's collection through iTunes, and might even look into using Vimeo and blip(dot)tv. You can also check out the organization's own web site, at LOC.gov, to see what's available.
